I figured out what the problem was: I had a version of polymake installed (3.0.6) and singular checks for a polymake install. However when I removed polymake and polymake-config from /usr/local/bin sage could be build successfully. When configuring singular one could also pass the --disable-polymake flag.
I hope somebody with a similar problem might find this useful.. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
